Embodiment Construction

[0024] Below, in conjunction with specific embodiment, the present invention is further described:

[0025] Rice planting techniques in saline-alkali land in Northeast China and soil improvement methods in severe saline-alkali land are as follows:

[0026] Land selection: choose land with abundant water, low nitrate content, not low-lying and prone to waterlogging, non-mud type, and PH value between 8.5 and 9.5, which is conducive to the growth of rice;

[0027] Planning of saline-alkali land: When planning the shape of the land, it is designed as a long strip, with an independent water inlet line as a channel for introducing water with low alkali content, and an independent drainage line as a channel for discharging water with high alkali content. The water source stays in the paddy field pond for 3 to 4 days. After the water stays for 3 to 4 days, the pH value of the water rises to above 8.5, and the alkali content of the saline-alkali land decreases to below the pH value of...

Abstract

The invention provides a northeast saline-alkali land rice planting technology and severe saline-alkali land soil improvement method. The method comprises saline-alkali land transformation and saline-alkali land planting, and the saline-alkali land transformation comprises land selection, saline-alkali land planning, soil improvement, saline-alkali land leveling and water source requirements. The saline-alkali land planting comprises seed selection, plowing, seedling raising time selection, rice transplanting and field management, and the field management comprises management of a rice seedling returning stage, a rice tillering stage, a rice jointing booting stage, a rice mature stage and a rice harvesting stage. According to the northeast saline-alkali land rice planting technology and severe saline-alkali land soil improvement method, the saline-alkali land can be effectively improved, meanwhile, high-yield planting of the saline-alkali land is achieved, and great significance is achieved for environment improvement.

Description

technical field [0001] The invention relates to the field of agricultural planting technology, in particular to the rice planting technology in saline-alkali land in Northeast China and the soil improvement method in severe saline-alkali land. Background technique [0002] The total area of ​​saline-alkali land in China is 99.13 million hectares, which is close to 1.5 billion mu of land. China's land red line is 1.86 billion mu. According to statistics, China imports soybeans, corn, wheat and rice from abroad every year, with a total tonnage of 140 million tons, equivalent to a planting area of ​​approximately 350 to 400 million mu. This part of the land is the land area that China is currently missing. Coupled with industrial land occupation and environmental pollution, the land is eroded, and the annual loss is 0.1% to 0.5% of the total amount of basic grain fields. The overall situation is not optimistic. [0003] Among the 1.5 billion mu of saline-alkali land in China...
